Bough a old about 1989 year, Hot springs classic. It is running on 110, one motor, the outside dial says automatic and can turn iit to jets. When turned to Jets, the motor comes on loud, but no water comes out of the jets, person I bought it from said he just had new moto jets put in. Stupid me bought it when it was empty so I could not try it out. I ran a hose down the filter pipe at full blast.

Think I replied to you on another subject section here. Try loosening one of the unoins ontop or infront of the jet pump to verify there's water in it and not air. if there's water in it and the pump runs and no water movement, -broken impellor. No big deal....serial#? starts with "F"-191234? Plenty of help from us or others here.
